# Three successive measurement in an experiment gave value 10.9, 11.4042 and 11.42 the correct way of reporting the average value is:

##### SOLUTION
${ V }_{ 1 }=10.9\\ { V }_{ 2 }=11.4042\\ { V }_{ 3 }=11.42$
Average value$= \cfrac {10.9+11.4042+11.42}{3}$
$=11.2414$
$=11.2$
$\therefore$ The  correct way of reporting the average value is $11.2$
